How do you know it is?
Also, everybody stop with the whole effin GFWL 2.0 crap.
Anybody that was thinking of buying the game for PC, hold off there will be a demo soon and hopefully by then this performance bug will be squashed.
Also for all those people going on about Phil Spencer and saying Windows 10 would support mods, he never said Forza Horizon 3 would. Before you go nuts wait until a AAA game is actually released on the Win10 store that is support to have mod support. If the DRM prevents that, then you can bitch about it.
Hey, hey buddy.
I'mma give you a hint about the PC world of gaming.
Here, in the PC land, it's assumed by "default" that a game is modable. Because when you have direct access to the file structure, it would be silly for it to not be modable. This goes back for as long as PC gaming has been around. A developer doesn't have to "state" the game has modding support (although really that would help). It's just a reality of the PC platform that modding is a thing.
Now, Microsoft (and many others) wish to take that away, because modding impairs their ability to sell you stuff after the fact, or enforce F2P style mechanics in single player games. There's no holistic "We're trying to protect the quality of gameplay" reason here. It's sacrificing everything that PC gaming has ever known in the never ending (and ultimately failing) battle against piracy on a platform that I can't imagine even has the sales numbers to justify it in the first place.
Edit: I just noticed LuvOfThaGame's entire post history since creation has essentially been running defense for anything and everything Xbox (and new age Microsoft by proxy). So I'm not really shocked at the attitude he's having towards PC gaming
